RECORD-CONTROLLED MACHINE.

Application led September 18, 1925. Serial No. 57,099.

This. invention relatesA to improved apparatus l'or record controlled or other machines and more particularly to devices Vfor rapidly converting a combination reading into a single reading. Previously rin reading combinational hole records the combinational holes were read with the record at rest and, thereafter, the combinational reading was converted into a single reading by mechanical n) devices to control subsequent machine opera-A tion. In other machines aA plurality of brushes were employed for reading the comy' binational record in which case the record could' be -in motion when the readings were la' taken.

v According to the present invention a single brush can be employed for sensing the records or other representation of a combinational reading while the representation is in motion. This brushcontrols translating devices which may include set-up contacts for temporarily retaining the combinational reading and afterwards translating the combinational reading into a single reading. The translating operation canbe eflfected by rotary devices whereby high speed operation can be obtained'.

These results are accomplished in myl Vpresent machine by electric devices sensing the combinational holes while the cards are vin motion, making set-ups-of contacts while the readings of the perforations'are being taken and then using those set-up contacts in connection with other devices toobtain a single reading having the same meaning in a device controlled by a single index point perforation as the combinational reading had in machines utilizing combination. hole records for control.

Fig. 5 is an end view.of the bottom half' Fig. 6 is a circuit diagram of the lelectric features of the device.v Although my invention may be used in connectionwith a varietyr of card-controlled devices I am for purposes of illustration` Showing it in connection with aHollerith type of accumulator, the outline of whichV is shown at 10 in Figs. land 3. y

Adjacent the accumulator is a framework Supporting most ofthe parts of the present invention. This framework'is not shown in full but is'represented by main plate 12 and supplementary plate 14.

Mounted on the main shaft 16 is a gear 18 driven by any outside source of power such as motor 2O represented diagrammatically in Fig. 6 which through a belt 22, shaft 24 and gear 26 drives gear 18. Gear 28 fast on shaft 16 through idler gears 30, 32 and 34 drives gear 36 fast on shaft 38 so that shaft 38 rotates at the same speed as shaft 16 both making one revolution per card cycle as does also shaft 40 on which are mounted the make and break cams 42 and 44 (Figs. 1, 3 and 6) lwhich operate the conventional make and break contacts 46 and 48 once per card cycle in the well known manner.

Fast 0n shaft 16 are four disk cams 50 each havinga small hump 52 and a larger hump 54. Underneath each cam 50 is a c0- operating horizontal lever pivoted at 62 and having an upstand'ng hump 64 directly x under shaft 16. Lever 60 is drawn upward by a spring 66. Resting on the free end of lever 60 is a vertical push rod 68'. l

Depending from each lever 60 is a Vertical arm having at its lower 'end a hookf72 and near its middle an armature 74 so placed that arms 70 are drawn t0 the right when magnet'76 is energized. vWhen magnet 7 6 is deenergized arm 70 is held to the left by a spring 7 8. 76 is a double magnet as shown in Fig. 4 and when it is energized all four arms 70 are drawn towards the right.

.For the purpose of illustration I am using the Peirce codefor numbers as shown in Fig. 2. This code comprises 4 index positions A, B, C and D and there maybe perforations in one or two of these positions to designate any particular number, as for instance, perforations at A and C mean 3; at

4B and D mean 4; at B and C the meaning is 8, while a single perforation means 2, etc.

As the cards are fed one by one from the supply magazine 80 between contact brushes 82 andco'ntact blocks 84 (Fig. .6), whenever a brush 82 finds a perforation a circuit is at B position Cams 50 are so set on shaft 16 that the hump formed as follows, 86 being'closed: line 88, contact 46, line 90,W brush 82, block 84. line 92, magnet 76 and back through line 94 to 95 which is the other side'of the line."

Thereis one brush 82 for each column of index pos.l tions on the card and I have shown three columns but more or fewer columns may be used if desired.

There is one set of four cams 50 for each :ard column and each of the four cams corresponds to one code positionv A, B, C or D.

. The cards are fed bottom first past the brushes. Consequently the brush onv any particular column comes in contact first with the A position, then B, C and D in order.

52- on any cam is at its lowest position in contact with hump 64 on lever 60 at the same instant the brush 82 is in .contact with the can move to the right that being the one which at that instant is depressed as in Fig. 5 by hump 52 on the cam 50 corresponding to that particular. arm 70. The other arms .7;0.

not being depressed are prevented from moving 4to the right by their hooks 72 abutting against the frame member 96.- After mag? nnet 76.v is deenergi'zed and hump 52 has passed out of contact with lever .60, all arms 7 0 which were not depressed when 76 was energizedfremain in the position shown in Fig. 1, Whereas the arm .70whfchwas depressed when-magnet 76 vwa'sfenergized is retained in depressed position by its hook 72 engagingV frame 96 as in Fig. 5.

If as the card passes down-past-the/'brush another hole is found in the same column the locked down.

The function of the mechanism just delarm 70 corresponding tothat'hole is also.

scribed isto controlupper and lower contacts 100 and 102. The insulated upper end of rod 68 which rests on the free end of lever 60 acts on spring blade I104 to hold upper contact 100 closed asin Fig. 1 Whenever lever down blade 104 opens lcontact 102. v

60 is in its higher position. Thisis the normal position of the parts, with Contact 100 closed. Whenever any varm is latched Contact 100 and 'closes .The parts lremain in latched Aposition as "above described. until releasing humps 54,0n all cams 50 depress all levers 60 and arms 7 0 and as 76 is not then energized allfarms 7 0 ,2re returnedto normal position by springs The above latching operations have taken place while the holes in the card were passing the brushes and at this point in the card cycle We have a lower Contact 102- closed, and an upper Contact 100 opencorresponding to each perforation found by the brushes.

The remaining part of the cycle will now be described. F astened rigidly to frame 12 ...is a plate 106 of bakelite or other non-concause they correspond tothe code positions bearing the sanne .designating-letters. This construction means thatbrushes A and B are` connected together electrically, and brushes C and D are likewise connected electrically.

'As shaft' 38 revolves it brings the above brush system into contact with strips 108 immediately after the contacts 100 and',` 102 have been set up as described, and'what then happens can best be understood-from diagram Fig. 6.

In Fig. 6 are shown diagrammatically three "sets of 50 cams, one set for each of the three:

card columns. 4

` The interrelationship of contacts 100, 102,1; strips 108 and the brushes-3A, B, .C and D is such that as arm 110's'weeps along strips 108 a circuit will be set upin each contact systemfat the proper time to actuate the differential mechanism ofthe accumulator in exactly'the same mannerv as if a Hollerith rsir'igle hole card were being analyzed andA accumulated; that is, asv vshaft `38 revolves the brushes on arm110pass the index positions set-ups already described -insure that any number set up will cause the accumulator clutch 140d`to be' engaged at the proper differential time to add the correct amount. y

This Acan best be, understood by considering some special set ups. For instance,` in the 'contact section of` Fig. 6 at the lett, lower contacts 1102 are closed at B and C positions'which means 8 in the Peirce code.v .With these contacts ,closed the brushes on arm-110 cannotcomplete a circuit until thc- 8 position is reached and at -thatpositiom in the-orderv 9, 8, 7, 6, 5', 4, 3, 2, 1,' 0,.and the shown-in the drawing marked 8 at the bot-i12 tom of Fig. 6,v a circuit is formed as follows :Al from upper-side of line 120, through wire 122, contact100 at D position, wire 124, strip 108.1to which12 4 is attached, D brush, C brush, strip 108, wire 126, lower contact 102 .at C position, lower contact 1102 at B .po-4
